Feene is the daughter of a mayor and lives in a remote village, near to the Gluttony Labyrinth. She also grew up with a former Disciple, Raoul, who is her childhood friend, who seems to have a crush on Feene, but she does not seem to reciprocate those feelings. She and Raul seem to be in a brother and sister like relationship.

It appears that Feene Glass is based upon Sonia Nevermind from Dangan Ronpa 2, another game from the company Spike Chunsoft, being as Feene and Sonia share some similarities. Both of them sharing a superior air to them, although modest about it, speaking politely and being quickly fascinated by new things or culture.
